Can you please do the following.

  1. stop ntopng
  2. $ redis-cli dump ntopng.prefs.user_scripts.configset_v3 > ntopng.prefs.user_scripts.configset_v3.txt
  3. $ redis-cli del ntopng.prefs.user_scripts.configset_v3
  4. restart ntopng

if it solves, then please send me the file ntopng.prefs.user_scripts.configset_v3.txt privately via mail at mainardi ntop org
